Title: New compositions of matter
IPC: C08L61/18
Filed: 1936-12-31
Abstract: Compositions for use in the manufacture of paints &c., plastic masses, luting materials, adhesives, moulding-compositions, flameproofing impregnants for cables and films, comprise a product obtained by condensing a partially chlorinated naphthalene with formaldehyde or a polymer thereof with which is incorporated a plasticizing or softening agent and/or a chlorinated hydrocarbon of high molecular weight.  Preferably, the partially chlorinated naphthalene contains not less than 20 per cent of chlorine. Suitable high molecular weight chlorinated hydrocarbons are chlorinated rubber or rubber hydrochloride, polymerized benzyl chloride, chlorinated naphthalene, chlorinated mineral oil and chlorinated wax.  The condensation may be effected in the manner described in Specification 4648/11, [Class 2 (iii)]; preferably powdered paraformaldehyde is added slowly to a mixture of sulphuric acid and chlorinated naphthalene and the mixture heated to 100-130 DEG  C. or above the melting point of the chlorinated naphthalene, if higher; the product being isolated by pouring into water or by a solvent.  At least 1, and preferably 2 mols. of formaldehyde per 2 mols. of chlorinated naphthalene is employed. Specified plasticizing or softening agents are ethyl, butyl, isopropyl, cyclohexyl, benzyl, methyl-benzyl and butyl-lauryl phthalates; corresponding esters of fumaric and succinic acid; and amides, e.g. tetrabutyl adipimide or tetraethyl phthalimide.  The ingredients may be incorporated by solution in a common solvent, by fusion followed by kneading &c.  Films may be obtained by flowing on to a flat surface a solution of the resinous product in benzene or toluene containing 5-10 per cent of a plasticizer, e.g. dibutyl phthalate; or by flowing the molten plasticized product on to such a surface.  Viscous coating-compositions may be obtained by dissolving the condensation product in toluene together with chlorinated rubber with or without chlorinated wax. Plastic masses may be obtained by melting the condensation product with chlorinated wax.  An example is given of the preparation of a resinous product by gradually adding 15 parts of powdered paraformaldehyde to a mixture of 250 parts chlorinated naphthalene containing 50 per cent chlorine and 300 parts concentrated sulphuric acid heated to 100 DEG  C., agitating for a further period, cooling the reaction mixture, extracting with trichloroethylene, neutralizing the extract, filtering through a bed of soda ash and distilling off the solvent.  Further examples include such resinous products incorporated with titanium oxide, chlorinated rubber, tricresyl phosphate or boiled linseed oil and solvents to form paints; dissolved with chlorinated rubber and chlorinated paraffin wax in trichloroethylene to form a stopping-off composition for use in electro-plating; and melted with chlorinated naphthalene, chlorinated rubber and chlorinated paraffin wax to form a plastic adhesive.

Title: The production of chemical fertilizers
IPC: C05B11/06
Filed: 1961-10-05
Abstract: The invention comprises a process for the production of chemical fertilizers in which rock phosphate is acidulated with an acid mixture comprising nitric acid-sulphuric acid, nitric acid-soluble soluble sulphate, or nitric acid-sulphuric acid-soluble soluble sulphate, which process comprises in a first stage adding to the acid mixture an amount of rock phosphate having a calcium content corresponding to 80-120% of the content of sulphate ion in said acid mixture, in a second stage adding to the slurry obtained from the first stage the remainder of the rock phosphates, and the slurry thus obtained is treated with ammonia, concentrated, granulated and dried. By controlling the calcium/sulphate ratio as above, calcium sulphate of large particle size is obtained, thus reducing the viscosity of the mixture and facilitating the filtration of the calcium sulphate if required.  Separation of the calcium sulphate may be done after the first or second acidulation stages.  Preferred soluble sulphates are potassium, ammonium, magnesium and manganese sulphates.  On separation of the calcium sulphate this compound may be washed and the washings obtained returned to the preparation of acid liquors, also a part of the slurry obtained from the first acidulation stage may be returned to the preparation of the acid liquors.  The first stage of the treatment may be modified by acidulating rock phosphate with nitric acid and then adding an acid mixture comprising sulphuric acid and/or soluble sulphates.  Specification 970,947 is referred to.

Abstract: 890,034. Knitting. PARTHUM, R. Oct. 29, 1959 [Nov. 1, 1958 ; Oct. 28, 1959], No. 36813/59. Class 74 (2). A run-resistant fabric is produced on a circular machine by providing flexible loop transferring elements 16 housed within inner and outer sleeve members 11, 10 and actuated by cams in a cam cylinder 22 as the needle cylinder and sleeves rotate so that the elements are projected to engage a loop on a needle and spread it over the adjacent needle to enable it to be taken by that needle when it is raised, Figs. 3, 4. The spreading action is achieved by there being slight relative rotation between the sleeves and needle cylinder. Alternatively the members may be actuated by separate members having butts actuated by cams on the outside of needle cylinder, a supplementary cam being provided which in the event of one butt on a member becoming inoperative actuates a second butt and in so doing operates a stop motion to stop the machine. The transfer elements may alternatively engage a loop of a preceding course and transfer that loop to the needle of an adjacent wale to be knitted with the next course, Fig. 19. A stationary tube having an upper funnelshaped end may be provided and within which the fabric is withdrawn from the needles. A gap is provided in the upper end of the tube to enable the loop transferring elements to project therethrough and in the event of an element failing to be withdrawn after it has been advanced it engages one edge of the gap in the tube causing the tube to slightly rotate, thereby actuating a stop motion. The needle slots may be wedge shape as illustrated in Fig. 12 to accommodate the needles.

Title: Space charge device for producing nuclear reactions
IPC: F25J3/04
Filed: 1959-10-30
Abstract: 903,870. Thermonuclear apparatus; discharge apparatus. STANDARD TELEPHONES & CABLES Ltd. (International Telephone & Telegraph Corporation). Oct. 30, 1959, No. 36890/59. Classes 39 (1) and 39 (4). A thermonuclear reaction chamber operative without applied magnetic fields, comprises electrodes arranged when suitably polarized to provide electrostatic means for oscillating particles along collision paths through a region of concentration of the particles in free space, the electrodes being arranged also for imparting increments of energy to the particles to replace energy of the particles lost by scattering. One arrangement, Fig. 1 (not shown), comprises a spherical photo-electric cathode enclosing a concentric spherical grid and an electron permeable spherical anode. Electrons released from the cathode tend to oscillate about the anode and form a virtual cathode at the centre of the apparatus. Gas, such as one or more of the isotopes of hydrogen at about 10<SP>-4</SP> mm. pressure, is admitted to the space inside the anode and is ionized by the electrons ; the ions oscillate inside the anode space and may collide and undergo thermonuclear reactions. The cathode may be of copper coated internally with aluminium or germanium and may be activated by ultra-violet radiation from the discharge. The apparatus may be surrounded by a cooling jacket containing water or heavy water and by a biological shield. In an alternative arrangement, Fig. 10, the electrodes do not form complete spheres. The cathode comprises the spherical shell 20a, and the grid 22a is of spherical configuration but having two segments removed from opposite sides which are reinforced by metallic rings 52, 53. The anode is in two sections each of which comprises three cup-shaped tungsten elements, the outer elements 57, 58 being connected together and the inner element 61 being insulated from the other two so that it can be maintained at a slightly different potential to form an electrostatic lens. Each anode section is supported from the cathode shell by a bellows member so that its position can be adjusted, and the envelope is provided with a gas inlet 33a and an exhaust duct 31a. The grid is operated with a small D.C. bias and a superimposed R.F. modulation of a frequency about 10<SP>8</SP> cycles/sec.; the effect of the R.F. modulation is to reinforce the oscillations of the ions and impart energy to them.

Classes 132(2) and 132(3) A toy repeating gun suitable for use with a toy shooting range R comprises arcuate portions 34 which guide a ball 40 as it is projected from the gun by means of a spring urged arm 38 pivoted at 41, the portions 34 having their inner edges upwardly converged to receive the ball; side guide portions 36 are provided but the ball is normally centred by the angular surfaces of the portions 34. A slidable trigger plate 48 carries a sear 54, the rear end 56 of which is adapted to bear against an abutment 58 of the arm 38 when the trigger is retracted. The arm 38 is thus pivoted rearwardly against the tension of a spring 42 until the rearmost ball 40 in a lower magazine barrel 84 moves by gravity and by means of a cam surface. on the trigger plate 48 into contact with a pad 76 mounted on the arm 38. The sear then clears the abutment 58 and the arm is allowed to fly forward, the ball being projected from the gun without touching the upper barrel 82. On its release, the trigger plate moves forwardly under action of a compression spring 64, the sear being able to move upwardly and to pass over the abutment 58. When the trigger has moved to its most forward position, the sear drops and is ready to move the arm 38 rearwardly as before. The body of the gun is preferably moulded of plastic and in halves, Fig. 6 (not shown). The gun is attached to the range by means of a stem 106 and a fulcrum bar 108 is prevented from being aimed downwardly by a visor 110 secured on the range. Balls not trapped in a target compartment 22 return by gravity into the magazine. The range has a transparent plastic housing 12.
